ed service engineers ONLY. Users are not permitted
to maintain it by themselves.
• The oximeter cannot be used together with devices
not specied in User’s Manual. Only the accessory
that appointed or recommendatory by manufacture
can be used with this device.
• This product is calibrated before leaving factory.
1.2 Warnings
• Explosive hazard—DO NOT use the oximeter in envi-
ronment with inammable gas such as some ignitable
anesthetic agents.

20
• The disposal of scrap instrument and its accessories
and packings(including battery, plastic bags, foams
and paper boxes) should follow the local laws and reg-
ulations.
• Please check the packing before use to make sure the
device and accessories are totally in accordance with
the packing list, or else the device may have the pos-
sibility of working abnormally.
• Please don’t measure this device with function test
paper for the device’s related information.
1.3 Attentions
Keep the oximeter away from dust, vibration, corro-
sive substances, explosive materials, high tempera-
ture and moisture.
If the oximeter gets wet, please stop operating it.
When it is carried from cold environment to warm or
humid environment, please do not use it immediately.

terials.
 High temperature or high pressure steam disinfection
of the oximeter is not permitted. Refer to User Manual
in the relative chapter for instructions of cleaning and
disinfection.

needs cleaning, please wipe its surface with medical
alcohol by soft material. Do not spray any liquid on
the device directly.
When cleaning the device with water, the temperature
should be lower than 60°C.
As to the ngers which are too thin or too cold, it
would probably affect the normal measure of the pa-
tients’ SpO2and pulse rate, please clip the thick n-
ger such as thumb and middle nger deeply enough
into the probe.
Do not use the device on infant or neonatal patients.
The product is suitable for children above four years
old and adults(Weight should be between 15kg to
ENGLISH

21
110kg).
The device may not work for all patients. If you are
unable to achieve stable readings, discontinue use.
The update period of data is less than 5 seconds,
which is changeable according to different individual
pulse rate.
If some abnormal conditions appear on the screen
during test process, pull out the nger and reinsert to
restore normal use.
The device has normal useful life for three years since
the rst electried use.
The hanging rope attached the product is made from
Non- allergy material, if particular group are sensitive
to the hanging rope, stop using it. In addition, pay
attention to the use of the hanging rope , do not wear
it around the neck avoiding cause harm to the patient.
The instrument dose not have low-voltage alarm
function, it only shows the low-voltage, please
change the battery when the battery energy is used
out.
When the parameter is particularly, the instrument
dose not have alarm function. Do not use the device
in situations where alarms are required.
Batteries must be removed if the device is going to be
stored for more than one month, or else batteries may
leak.
A flexible circuit connects the two parts of the
device. Do not twist or pull on the connection.
1.4 Indication for Use
The Fingertip Pulse Oximeter is a non-invasive device
intended for the spot-check of oxygen saturation of
arterial hemoglobin (SpO2) and the pulse rate of adult
and pediatric patients in home and hospital environ-
ments (including clinical use in internist/surgery, anes-
thesia, intensive care ect.).
This device is not intended for continuous monitoring.
ENGLISH

22
2 OVERVIEW
The pulse oxygen saturation is the percentage of HbO2
in the total Hb in the blood, so-called the O2concen-
tration in the blood. It is an important bio-parameter for
the respiration. For the purpose of measuring the SpO2
more easily and accurately, our company developed the
Pulse Oximeter.
At the same time, the device can measure the pulse rate
simultaneously.
The Pulse Oximeter features in small volume, low power
consumption, convenient operation and being portable.
It is only necessary for patient to put one of his ngers
into a ngertip photoelectric sensor for diagnosis, and a
display screen will directly show measured value of He-
moglobin Saturation.
2.1 Features
• Operation of the product is simple and convenient.
• The product is small in volume, light in weight (total
weight is about 50g including batteries) and conven-
ient in carrying.
• Power consumption of the product is low and the two
originally equipped AAA batteries can be operated
continuously for 24 hours.
• The product will automatically be powered off when no
signal is in the product within 5 seconds.
• Low-battery indicator as battery icon ash manner.
2.2 Major Applications and Scope of Application
The Pulse Oximeter can be used to measure human He-
moglobin Saturation and pulse rate through nger, and
indicate the pulse intensity by the bar-display.
The product is suitable for use in family, hospital (Ordi-
nary sickroom ), Oxygen Bar, social medical organiza-
tions and also the measure of saturation oxygen and
pulse rate.
ENGLISH

23
The product is not suitable for use in continu-
ous supervision for patients.
The problem of overrating would emerge
when the patient is suffering from toxicosis
which caused by carbon monoxide, the de-
vice is not recommended to be used under
this circumstance.
2.3 Environment Requirements
Storage Environment
a) Temperature: -40°C~+60°C
b) Relative humidity: ≤95%
c) Atmospheric pressure: 500hPa~1060hPa
Operating Environment
a) Temperature: 10°C~40°C
b) Relative Humidity: ≤75%
c) Atmospheric pressure: 700hPa~1060hPa
3 PRINCIPLE AND CAUTION
3.1 Principle of Measurement
Principle of the Oximeter is as follows: An experience
formula of data process is established taking use of
Lambert Beer Law according to Spectrum Absorption
Characteristics of Reductive Hemoglobin (Hb) and
Oxyhemoglobin (HbO2) in glow & near-infrared zones.
Operation principle of the instrument is: Photoelectric
Oxyhemoglobin Inspection Technology is adopted in
accordance with Capacity Pulse Scanning & Recording
Technology, so that two beams of different wavelength
of lights can be focused onto human nail tip through per-
spective clamp nger-type sensor.
Then measured signal can be obtained by a photosensi-
tive element, information acquired through which will be
shown on screen through treatment in electronic circuits
and microprocessor.

Figure 1. Operating Principle
3.2 Caution
1. The nger should be placed properly (see the at-
tached illustration of this manual, Figure 5), or else it
may cause inaccurate measurement.
2. The SpO2sensor and photoelectric receiving tube
should be arranged in a way with the subject’s arteri-
ole in a position there between.
3. The SpO2sensor should not be used at a location
or limb tied with arterial canal or blood pressure cuff
or receiving intravenous injection.
4. Make sure the optical path is free from any optical
obstacles like rubberized fabric.
5. Excessive ambient light may affect the measuring
result. It includes uorescent lamp, dual ruby light,
infrared heater, direct sunlight and etc.
6. Strenuous action of the subject or extreme electro-
surgical interference may also affect the accuracy.
7. Testee can not use enamel or other makeup.
3.3 Clinical Restrictions
1. As the measure is taken on the basis of arteriole
pulse, substantial pulsating blood ow of subject is
required. For a subject with weak pulse due to shock,
low ambient/body temperature, major bleeding, or
use of vascular contracting drug, the SpO2waveform
(PLETH) will decrease. In this case, the measurement

will be more sensitive to interference.
2. For those with a substantial amount of staining dilu-
tion drug (such as methylene blue, indigo green and
acid indigo blue), or carbon monoxide hemoglobin
(COHb), or methionine (Me+Hb) or thiosalicylic he-
moglobin, and some with icterus problem, the SpO2
determination by this monitor may be inaccurate.
3. The drugs like dopamine, procaine, prilocaine, li-
docaine and butacaine may also be a major factor
blamed for serious error of SpO2measure.
4. As the SpO2value serves as a reference value for
judgement of anemic anoxia and toxic anoxia, some
patients with serious anemia may also report good
SpO2measurement.
